Hydraulic Radius of a Pipe

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

hydraulic radius of a pipe less than halfHydraulic radius, abbreviated as \(r_h\), is the cross-section area of water in a pipe or channel divided by the wetting perimeter.

 

Hydraulic Radius of a Pipe formula

\(\large{ r_h =  \frac  {  A_c }  { P }   }\)   

Where:

\(\large{ r_h }\) = hydraulic radius

\(\large{ A_c }\) = area cross-section of flow

\(\large{ P }\) = wetted perimeter
